Electrode foil for capacitors and solid electrolytic capacitor |
摘要 |
A solid electrolytic capacitor that includes a cathode foil and solid electrolyte made of conductive polymer. This cathode foil is made by providing a nickel layer on a surface of a base material made of valve metal. This nickel layer includes a layer containing only nickel and a layer containing nickel oxide. Both large capacitance and low equivalent series resistance are achievable at the same time with this simple structure at low cost.
